Threadlocker Blue Stick 9g/.30oz

Loctite Threadlocker Blue Stick 9g/.30oz (SKU LOC506166) is a removable threadlocker designed for fastener assembly and maintenance in mechanical systems. Blue 242 formulation prevents fasteners from loosening due to vibration while remaining fully removable with standard hand tools, making it the preferred choice for applications requiring periodic disassembly without specialized equipment.

The 9g stick format offers precise application control without mess or waste. Users dispense the adhesive directly onto fastener threads by turning or pressing the stick onto the bolt head or screw. Medium-strength formulation (242 grade) creates a reliable seal that holds under moderate vibration while allowing disassembly with ordinary wrenches or screwdrivers. Unlike liquid variants, the stick eliminates drips, over-application, and cleanup time—critical for field work, equipment maintenance, and rapid repairs where accuracy and convenience matter.

This threadlocker serves mechanics, technicians, shooting sports enthusiasts, and tactical professionals who maintain firearms, optics, vehicle systems, and mechanical gear. Applications include scope mount screws, rail fasteners, handguard attachments, charging handle pins, stock hardware, and any bolt connection subject to vibration or thermal cycling. The stick format is ideal for field kits, go-bags, and portable maintenance packs where compact size and mess-free delivery are essential.

Blue threadlocker sits between permanent red formulations and lightweight thread sealers—it balances security with serviceability. The 9g/.30oz size provides multiple applications before replacement, offering better value than small tube formats while remaining portable enough for range bags and emergency repair kits.
